Projections extending from the cell that usually appear alone and help propel an entire cell are ____________ . The only example of a cell with a flagellum is ____________ .

Answer 1

Cilia and flagella are projections extending --from the cell. Projections extending from the cell that are usually found in cells in the respiratory passageways are --cilia . Projections extending from the cell that usually appear alone and help propel an entire cell are --flagella . The only example of a cell with a flagellum is --euglena .

Answer 2

Cilia and flagella are projections extending from the cell.

Projections extending from the cell that are usually found in cells in the respiratory passageways are cilia .

Projections extending from the cell that usually appear alone and help propel an entire cell are flagella.

The only example of a cell with a flagellum is sperm/bacteria cell.

Step-by-step explanation:

Cilia are organelles which are present in eukaryotic organisms which protrude outwards from the cell. They are of two types- Motile and Non Motile. The non motile cilia cannot move and have a role in sensory function. The cilia are present outside the respiratory tract and help flush microbes and debris out of the passage way.

Flagellum or flagella help in the locomotion many bacteria and eukaryotes. These are filamentous protein structures which come out of the cell body. Few examples of organisms having flagella is bacteria and in eukaryotes it is the sperm cell.
